It was a great day out on the water! They had everything you needed to snorkel or dive. All of the guides on the boat were knowledgeable and passionate about the reef. Even the food/snacks were great (and I’m a picky eater)! EVEN IF YOU DO NOT USUALLY GET SEASICK, take a motion sickness pill before you go. So many people were getting sick while traveling out to the reef. It was not pleasant.

Everything went smoothly with checking-in and boarding. Due to the weather we only went to two different sites at the reef, but we had plenty of time to do two “dives” at the first site if we wanted to. We saw a lot of different sea creatures, including a shark, stingray and a turtle! The sites at the reef were wisely chosen for snorkeling, as they were close to the surface. We have scuba dived before, but didn’t feel the need as you were on the same depth as most of the fish. A bonus was lunch was very good, especially the Japanese curry! The staff were friendly and informative, and made sure everyone had a good time. If you go during winter I would recommend bringing some spare warm clothes or extra towels as it got pretty cold after snorkeling. The water was 25 degrees, so we didn’t get cold while snorkeling, just after.

Amazing tour, so much fun and the staff were incredible. Very attentive, friendly and helpful. It's just a shame they charge so much for pictures. $86 for 3 pictures is pretty disrespectful considering how much the experience costs. Otherwise it's great!
